presses, such as are used for newspaper work and some magazine work.

Objects and advantages of the invention will be set forth in part hereinafter, and in part will be obvious herefrom, or may be learned by practice with the invention; the same being realized and attained through the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, arrangements, constructions, combinations and improvements herein shown and described.

The accompanying drawings. referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description serve to explain the principles of the invention.

Of the drawings Figure 1 is a fragmentary side elevation, partly diagrammatic, of the inking mechanism and a rotary printing couple of a printing press embodying the invention;

Fig. 2 is a fragmentary end elevation, with parts in section, looking at Fig. 1 from the right;

Fig. 3 is an enlarged fragmentary detail, partly in. section, of the connecting rod or links in the ductor roller control mecharoller in its carrying arm and in the con trolling or adjusting slide.

Referring now in detail to the embodied mechanism, illustrated. by way of example 1n the accompanying drawings, a rotary printing-couple is represented having a form cylinder 1 with its shaft 2 running in bearings 3, and a cooperating impression cylinder 4, having a shaft 5 running in bearlngs 6. The web m runs through between the cylinders in the usual manner, and is prlnted upon by the plates upon the form cylinder 1. i

In accordance with one feature of the .invent on, and as previously indicated, an interm ttently rotatable fountain roller is provided, although so far as concerns many features of the invention, a continuously rotatlng fountain roller could be utilized. In the embodied form thereof a fountain roller 10 is provided operating in an ink fountain 11. The intermittently operating actuating means for the ductor roller may be of any suitable or adequate form, and as illustrated herein, a shaft 12 is j ournaled in suitable brackets 13 mounted on the machine frame, and carried on shaft 12 is a cam 14. Cooperating with the cam 14: is k a longitudinally-reciprocating rack bar 15, and carried by saidfrack bar 15 isa cam roller 16, which roller cooperates with the cam 14.. .The cam roller 16 is fixed to the.

bar 15 in a suitable manner, as by a bolt V The rack bar 15 has fixed thereto at 18 a longitudinally 7 extending guide rod 19, which guide rod works in a guiding aperture in the brackets or lugs 20 fixed to the machine frame. Thus as the shaft 12 rotates rack bar 15 and guiding rod 19 are vertically reciprocated (Fig. 1).-

Rack bar 15 is provided with a series of teeth 21, which teeth mesh with a toothed sector 22, carried loosely upon a shaft 23. A roller 24 is mounted in the bracket 20, and bears against the back of the rod 15 to hold it to its work. F ixedto reciprocate with the geared sector 22 is a pawl lever 25 provided with a pawl 26. The pawl 26 co operates with a ratchet wheel 28, which ratchet wheel is fixed uponthe shaft 23 of the fountain ink roller 11. Thus as the rack bar 15 reciprocates, the pawl 26 is oscillated to and'fro, thereby imparting intermittent rotary movement to the ink fountain roller 11. Suitable means for varying the throw or travel of'the pawl 26 or of its engagement with ratchet wheel 28, are provided,

but are omitted from the drawings for the sake of clearness, together with other. details of theassociated mechanism.

In accordance with certain features of the invention, and as herein embodied, a plurality of ductor rollers are preferably provided, and in accordance with one feature of the invention the ductor rollers travel in an endless circular path, the ductor rollers yielding or moving radially, so as to travel along the periphery of the ink drum, of the fountain roller, or of both. In conjunction and coiiperation with the foregoing there are provided means for governing the length of the path of travel of the ductor rollers upon or along the periphery of either the,

ink drum or the fountain roller, such means in accordance with certain features of the invention being mounted upon the ductor roller carrier, and preferably upon the shaft I from which the ductor rollers are supported and around which they rotate. Referring to the details of the present embodiment, and having inmind the pref- 7 box is j ournaled the shaft or pintles 41 of the corresponding ductor roller 42.

The embodied form of resilient means for permitting radial movement of the ductor roller 42 to capacitate it for traveling about the periphery of the ductor roller, or the ink drum, or both, comprises a spring 43 in compression between the inner end of each of the apertures 39 and the corresponding sliding journal box 40 of the ductor roller.

The embodied form of means forcontrolling or regulating the ink supply by varying or governing the extent or distance of the travel of the ductor roller along the PG? riphery of the ink drum, or the fountain roller, or both, comprises devices mounted upon. the duct-or roller carrier for moving the ductor roller radially, or for limiting its outside or extreme radial position under the impulsion of the spring 43'. In the present case this means controls or operates all four ductor rollers. As embodied, a frame 50 is slidably mounted upon each of the arms 35,

36, 37 and 38, the frame 50 having an aperture 51 formed therein in alinement with the aperture 39 in the arm it"elf, but being movable with respect thereto. The corresponding journal boX 40 of the ductor roller is slidable within the aperture 51-as it is within the aperture 39 previously described. As embodied the cooperating portions of this mechanism for varying or governing the actionof the ductor rollers are carried upon the shaft 34. The entire mechanism is controlled by through settable devices connected to and operating the mechanism, such devices being mounted in stationary position varying the positionof each ductor roller in cooperation with the foregoing described means for varying and controlling them collectively. To effect this, as embodied,each link 54 is provided with'a threaded sleeve or turn-buckle 57, to vary the length of the link and thereby to regulate the position of the particular ductor roller with respect to the fountain roller and the ink drum and also with respect to, the other ductor roller. This enables achustment to be inide for difference in shrinkage between different rollers, as well as providing for other varia tions and differences.

The settable devices controlling the fore-' going described mechanism and mounted in stationary position upon the machine frame comprise a lever 58, pivoted upon the frame at 59, and having a yoked end 60 straddling the collar 56, and having pins 61 projecting into an annular groove 62 formed in the sleeve56. A quadrant or segment plate 63 may be mounted on the machine frame, and suitably scaled or marked, and means for fastening the lever 58 in position may be provided such as a clamping nut 64 operating in a slot 65 in the quadrant 63. This mechanism is duplicated at the opposite side ofthe machine. Thus a uniforman'd exact adjustment may be provided or effected at each side of the machine for both ends of the ductor roller. 7

The ink drum 7() shown herein as cotiperating with the ductor rollers, and taking the ink therefrom to be forwarded and applied to the printing plates upon the cylinder 1, may represent any desired elementor member in the inking system which is adapted to receive the ink from the ductor roller and to participate in its distribution, forwarding and supply to the printing plates on the form cylinder, the remaining parts of the inking mechanism being shown herein more'or less conventionally.

The ink drum cooperates With a form inking roller/71 Which supplies ink to the 1 plates upon the form cylinder 1, and also 7 Suitable vibrating mechanism is provided for vibrating certain or all of the members described. y

In the embodied form of inking means a shaft 12 has mounted thereon an eccentric 86, thestrap 87 of which is connected to a rod 88 through Which the eccentric actuates the vibrating mechanism. Rod 88 is pivotally connected to an arm 89 fixed to a shaft 90, Which shaft is'journa-led in av bracket 106 mounted on the machine frame; Fixed to the shaft 90 is an arm 91, having at its outer end a roller 92 Working in a grooved collar 93 fixed on the shaft 94 of roller 74. Fixed also to shaft 90 is a geared sector 95 which intermeshes With the geared sector 96, fixed on a shaft 97, journaled in a bracket 107 mounted on the machine frame. Fixed to shaft, 97 is an arm 98 having at its outer end a roller'99 orking in a grooved collar 100, fixed on the shaft 101 of the ink drum 70. Fixed also to shaft 97 is an arm 102 having at its outer end a roller 103 Working in a grooved collar 104, fix'ed to the shaft 105 of ink drum 72. r V

The mechanism as embodied regulates or determines the extent of the travel of the ductor roller on the peripheries of both the fountain roller and of the ink drum, as already described, by regulating and varying the position of the ductor'r'oller along its arms. If it'be desired to vary the ink transferringaction as between the fountain rollerand theink drum, as for instance by shortening the travel of the ductor roller on the ink drum While maintaining the same amount of ink delivered from the fountain roller to the ductor roller, it isonl'y'necessary to increase thethrow of the fountain roller-by, means of the ratchet 26. The" reverse action from this, as Well as any other desired variation of-theactionat the fountain roller and ink drum will be clear from the foregoing. V
